Wasn't the whole point of the original TPP to limit China's power in the region by establishing more close trade relations for the other countries in the region?
Would adding China to it not defeat that entire point and just make everyones China's bitch, like how Brexiteers complain Germany does in the EU and why they need to get out?
Also it completely ignored the question if the countries in the CTPP even want the UK, considering its on the other side of the globe by its lonesome...
Sounds like more unicorns.
